IVILLIAM S. MEAD, OF BUFFALO, NEW YORK.

APPARATUS FOR GENERATING VAPOR IN LAIVEPS.

Specification of Letters Patent No. 27,061, dated February 7, 1860.

To all whom it may concern:

Be it known that I, WILLIAM S. MEAD, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Fluid-Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention relates more particularly to the constructionand arrangement of the gas generating and regulating apparatus.

In the annexed drawings Figure 1 repre sents a longitudinal section. Fig. 2 repre' sents a portion of the apparatus in section. Fig. 3 is a detached View of the burner. Fig. 4: is a View of the burner and a portion of two pipes.

It will be understood before entering upon a description of the several parts of my improvement that they are to be used in connection with an elevated reservoir for supplying etherial oil, or common burning fluid, to the generating apparatus.

In the annexed drawings A represents a pipe through which the oil is conducted from the reservoir to the gas generating apparatus. The lower end of this pipe connects with a shell or case G, in which is contained a stop cock F. This case is provided with a recess marked H, in which is placed a screw 6, which passes into one end of the cock F, and secures it firmly and securely to said case. The cock F, is provided around its periphery, or partially around its periphcry, with a V shaped or tapering groove, as is seen in Fig. 2. From the large part of this groove a hole passes into the center of the cock and connects with a hole, which passes out at the end of the cock and through the screw into the recess H. The object of the hole through the cock is to admit the oil, allowing it to pass from the reservoirs into the pipe A,-and the object of the tapering groove is that by means of it a greater or less amount of the oil may be admitted into the said pipe A.

0 represents the heater which consists of a tapering cylinder which is open at both ends, and which is screwed onto the top of the pipe A.

a, represents the frustum of a cone, which is surrounded with a spiral thread. One end of this frustum is provided with a screw 'the heater at the other end of said frustum and in passing from one end to the other it is compelled to follow the spiral thread. Thus it is made to pass several times around the frustum and is thoroughly converted into gas by the time it reaches the mouth of pipe B.

A projecting plate J, extends out from the heater C, for the purpose of catching and retaining heat from the burner which stands a short distance below and under this plate.

The burner m is secured to a metallic piece which connects with the pipe B, and which is made to surround the pipe A, as is seen in the figures. The object of having this metallic piece E, surround the pipe A is that heat may be communicated to the said pipe from the burner m, thus partially heating the oil as it passes up said pipe.

I do not propose to use any specific kind of wicking for this lamp, as I may use any kind in ordinary use. I think it highly probable though that I shall use a wire wickthat is a wick composed of a number of small wires placed close enou 'h together to create capillary attraction suhicient to prevent a too rapid passage of the'oil up the pipe A, at the same time allowing it a free passage.

2, is a rough rod in pipe A.

n, represents a small screw which passes into the metallic piece E, and closes an opening into the gas passage. The object of having this screw at this point is to clean out the gas passage to the burner when necessary.

The main pipe leading from the reservoir connects with the case G, at the recess H.

It will be seen that the frustum a, may be removed at any time and cleaned by simply removing the nut cl.

0 represents a small screw which closes an opening to the pipe B, which is also used for the purpose of cleansing said pipe when necessary.

This apparatus is so constructed throughout that it may be taken to pieces in a few moments and any of its parts cleaned 01 cleared of any residuum Which may be found in the heater C, the same being used subin them. stantially as and for the purpose specified.

Having thus fully described my invention What I claim as new and desire to secure by MEAD 5 Letters Patent is V Witnesses:
